Roger,
I think you're observations propagation are correct, but I strongly
disagree with the paragraph below. My experience has been that IF the
antenna is accurately modeled, ground characteristics accurately
represent where the antenna is rigged, and the appropriate NEC ground
model is
I fully agree with the statements below. *Most* of the time, a vertical is
superior for DX on 160m. Please see:

Well I've said it dozens of times before . . . but I have used a horizontal
halfwave Dipole (at about 50ft)
for working DX on 160m for the past 50 years ! (and that's at 6 different
QTHs)
Not only do I work

Not only do I work all over the world, but I know my signal often compares
pretty well with other Gs using

For those who are antenna challenged, don't sell a 160m inverted-vee at low
height too short.
My 160m antenna at the moment is an inverted-vee at an apex of 45 feet.
Additionally, the last third of each end is at 90 degrees to the main
port

When I decided on the new challenge of working DXCC on 160 for my ninth band, I
added some extensions on my 80-meter inverted-vee , (apex at 45') and tied them
off on some handy saguaro cacti about head high. You don't climb these :-) I
worked my first 80 or so countries with it. And this is

Hi Ed,
I've studied this extensively for horizontally polarized antennas, but
only for flat ones; I thin that inverted Vees have some vertical
components.
For horizontally polarized antennas, maximum gain at high angles occurs
at a mounting height of about 75 electrical degrees, and falls
I was reminded of my interest in re-installing a low 160M antenna to
supplement by 2 el vertical phased array. And since there was no where to
go this weekend and no College Hoops to watch, I thought, hey, I could get
something up and play around with it in the Spring Stew. And that what I
did.
